Overall, I highly recommend this product to potential purchasers.
I bought this product from an Amazon competitor because I needed it quickly and it was not in stock. Of course, I paid more for both the item and shipping (about $400 total).
Pros: 1) At the time of purchase (October 31, 2009), the Acer T230H is the largest multi-touch display available.
2) It brings out the multi-touch capabilities of any Windows 7 laptop/desktop.
3) It can be moved from computer to computer as needed. We have tested it on both laptops and desktops running Windows 7 and it performs flawlessly.
Cons: 1) I was not able to complete the calibration routine as part of setup. I had difficulty getting the T230H to recognize the lower left calibration corners using a stylus from a Windows XP Tablet computer. I canceled calibration and used the factory settings. The T230H reads the lower left corners fine with its factory settings so this is really not an issue.
2) The unit is much more expensive than a regular 1920x1080 display. I'm sure it will come down in price as more vendors carry it.
3) For best results (individual use), the T230H requires something like an Ergotron arm so that the screen is better positioned for touch input (positioned more like a keyboard resting on the desktop). However, the unit is great for demonstrating multi-touch applications to others when using its included stand. For more ideas about using the T230H with an Ergotron arm see the terrific post at the Green Button by htpc2009 who covers using the HP 2105TM as a controller for Windows 7 Media Center.
4) The display includes a 3-year carry-in warranty while the HP 2105TM and Dell SX2210T take better care of their users.
I look forward to reading about other people's experience with this outstanding multi-touch display. Acer T230H bmidh 23-Inch Wide Touch Screen Display - Black
I just purchased a new computer with Windows 7 and wanted an nice High-Definition screen to go along with it and settled upon the Acer T230H. I mostly wanted a fantastic screen for surfing the web, writing reports, and watching movies and frankly the touch was just a nice extra feature. It is an "Optical Touch Screen". In other words, it uses two infra-red sensors in the upper left and upper right hand corners to sense where your finger(s) (or any object actually) are on the screen.
The Touch-
It is not quite as accurate as the iPhone's touch screen but then again everything is bigger on a 23" screen lol. It does however work with the back of pencils, pens, corners of paper, tops of water bottles, actually just about any solid object can be used to interact with this touch screen. As far as I know, the iPhone can only respond to skin on screen interactions. The touch actions themselves on the T230H are very responsive with little effort at all. You can even bring your finger very close to the surface without touching the screen and the computer will respond to your position and click wherever your finger is about 1mm above the surface of the screen. I still find myself using the mouse often because I don't want to raise my arms for long periods of time. One area the touch has great potential is when viewing/editing photos. It is very helpful to just "flick" between photos and also to zoom and rotate photos. Using it to scroll on web pages is also fun and often easier than clicking on the bar or up/down arrows on the left of the browser.
This monitor comes with a screen that rotates on the base left or right, can be moved up and down, or angled up or down. It helps so you don't hurt your neck looking up or down depending upon your height and seating arrangement.
The screen is excellent, very clear, high-contrast, and of course is best used with High-Def (1080) resolution. The monitor has multiple settings such as "TEXT", "GRAPHICS", and "MOVIE". The "TEXT" setting is definitely easier on the eyes when reading for long periods.
I liked the screen enough to purchase again and now I have two Acer T230H's next to each other. Yes, with Windows 7 and a compatible graphics card you can have a dual High-Def touch monitors! You can drag windows from one screen onto the other and then "grab it" with your finger on the other screen and put it where you want.
After all my bragging here are some Cons:
1) Speakers suck. Volume barely loud enough to hear if you have any background noise whatsoever. Definitely need external computer speakers if planing to listen to music, watch movies, etc.
2) The optical touch system require extra thickness and hence the screen are not as thin as most high quality non-touch LCDs.
3) No LED backlight.
--------------------------------------------
Conclusion-
Overall I had no problems other than a stuck base that needed a good firm twist to loosen up so I could rotate the screen left-right at will. I strongly recommend this monitor to anyone who wants to "touch" the future of the computer for themselves and see in High-Definition. - Multi-touch - Windows 7 - 1920x1080 - Monitor'
